Modular wearable medicament delivery device and method of use thereof

Abstract

A medicament delivery device and method of use thereof. The device includes a sensor module and an injector module. The injector module is adapted to (i) be coupled to the sensor module during injection of a cannula and a needle into subcutaneous tissue and during delivery of the medicament and (ii) be removed from the sensor module after the delivery of the medicament.

What is claimed is: 
     
       1. A medicament delivery device comprising:
 a sensor module comprising:
 a sensor housing, and 
 at least one sensor disposed in the sensor housing; and 
 
 an injector module comprising:
 an injector module housing, 
 a reservoir disposed in the injector module housing, the reservoir adapted to be filled with a medicament to be delivered to a patient, 
 a cannula adapted to (i) fluidically connect with the reservoir and (ii) pass into a subcutaneous tissue, 
 a needle initially disposed in a lumen defined by the cannula and adapted to pass into the subcutaneous tissue, and 
 a coupling mechanism adapted to couple the injector module to the sensor module, the coupling mechanism comprising a latch, 
 
 wherein the injector module is adapted to (i) be coupled to the sensor module during injection of the cannula and the needle into the subcutaneous tissue and during delivery of the medicament and (ii) be removed from the sensor module after the delivery of the medicament. 
 
     
     
       2. The medicament delivery device of  claim 1 , wherein the at least one sensor comprises at least one of a temperature sensor, an accelerometer, a gyroscope, a pulse oximeter, a blood pressure sensor, a hydration sensor, a pH sensor, glucose sensor, or a UV exposure sensor. 
     
     
       3. The medicament delivery device of  claim 1 , wherein the at least one sensor is disposed on a bottom surface of the sensor module and is configured to be in contact with the skin surface when the adhesive patch is connected thereto. 
     
     
       4. The medicament delivery device of  claim 1 , wherein the sensor module defines a recess adapted to mate with the latch. 
     
     
       5. The medicament delivery device of  claim 1 , wherein the coupling mechanism comprises a push button adapted to move the latch between an engaged position and a disengaged position. 
     
     
       6. The medicament delivery device of  claim 5 , wherein the push button extends through a portion of the injector module housing. 
     
     
       7. The medicament delivery device of  claim 1 , wherein the sensor housing of the sensor module defines a needle port. 
     
     
       8. The medicament delivery device of  claim 7 , wherein the cannula is further adapted to pass through the needle port of the sensor module. 
     
     
       9. The medicament delivery device of  claim 7 , wherein the needle is further adapted to pass through the needle port. 
     
     
       10. A method for delivering a medicament, the method comprising:
 connecting to a skin surface a medicament delivery device comprising an injector module coupled to a sensor module comprising at least one sensor, wherein (i) the injector module comprises a reservoir containing the medicament, and (ii) the injector module comprises a coupling mechanism adapted to couple the injector module to the sensor module, the coupling mechanism comprising a latch; 
 delivering the medicament from the injector module into a subcutaneous tissue; and 
 after delivery of the medicament, removing the injector module from the sensor module. 
 
     
     
       11. The method of  claim 10 , wherein the injector module further comprises a cannula in fluidic communication with the reservoir, and delivering the medicament comprises passing the cannula into the subcutaneous tissue. 
     
     
       12. The method of  claim 11 , further comprising leaving the cannula in the subcutaneous tissue after delivery of the medicament. 
     
     
       13. The method of  claim 11 , wherein the injector module further comprises a needle disposed in a lumen in the cannula, and delivering the medicament comprises piercing the skin surface with the needle prior to passing the cannula into the subcutaneous tissue. 
     
     
       14. The method of  claim 10 , further comprising monitoring a biometric parameter with the sensor module. 
     
     
       15. The method of  claim 14 , wherein the biometric parameter is monitored after the injector module is removed. 
     
     
       16. The method of  claim 14 , wherein the biometric parameter comprises at least one of temperature, oxygen level, blood pressure, hydration, pH, glucose, or UV exposure. 
     
     
       17. The method of  claim 10 , wherein the sensor module defines a recess adapted to mate with the latch. 
     
     
       18. The method of  claim 10 , wherein the coupling mechanism comprises a push button adapted to move the latch between an engaged position and a disengaged position. 
     
     
       19. The method of  claim 10 , wherein the medicament comprises pegfilgrastim.
